Product Description
Product Description of Blast Furnace Throat Castable
The primary function of the blast furnace throat is to protect the furnace lining and ensure proper material distribution. During normal operation, the temperature in this area is between 400–500°C. The throat is mainly subjected to direct impact and abrasion from the burden material, while the gas flow erosion is relatively mild. Therefore, the throat area typically uses water-cooled or non-water-cooled steel bricks (cast steel parts). For water-cooled steel bricks, castable refractory material is filled between the brick and the furnace shell, whereas non-water-cooled steel bricks are installed with castable material as part of the construction process.
Steel fiber-reinforced castable is made using bauxite clinker as aggregate, with bauxite clinker and corundum fine powder as the matrix. It uses ultra-fine powder and various composite materials as binders and additives, combined with stainless steel heat-resistant fibers. The addition of steel fibers significantly enhances the overall strength of the furnace wall after casting.
Rongsheng Refractory has more than 20 years of experience in producing castable materials, optimizing production processes for various industry applications to ensure that all quality indicators meet high standards. We welcome customers to contact us for inquiries!
